Abstract

Es wird eine Einrichtung zum Angleichen von Meßergebnissen zwischen einem ersten, als Referenzgerät dienenden Gasanalysator und einem zweiten Gasanalysator (10) mit einer Meßanordnung vorgeschlagen, deren ermittelten Untersuchungsergebnisse in einer signalverarbeitenden Anordnung auswertbar sind, mit einer Gaseinlaßöffnung (13) und einer Gasauslaßöffnung (15). Dabei ist ein eine Gaseinlaßöffnung (14) und zwei Gasauslaßöffnungen (18, 20) aufweisender Hohlkörper (21) vorgesehen, dessen erste Gasauslaßöffnung (18) mit der Gaseinlaßöffnung (13) des zweiten Gasanalysators (10) kommuniziert, während die zweite Gasauslaßöffnung (20) ins Freie (24) bzw. in die Gasauslaßöffnung (15) des Gasanalysators (10) führt und eine definierte Größe aufweist.

A device for matching measurement results between a first gas analyzer serving as a reference device and a second gas analyzer (10) with a measurement arrangement is proposed, the determined test results of which can be evaluated in a signal processing arrangement, with a gas inlet opening (13) and a gas outlet opening (15). . A hollow body (21) having a gas inlet opening (14) and two gas outlet openings (18, 20) is provided, the first gas outlet opening (18) of which communicates with the gas inlet opening (13) of the second gas analyzer (10), while the second gas outlet opening (20) leads into the open (24) or into the gas outlet opening (15) of the gas analyzer (10) and has a defined size.
